Jay Leno, no surprise, is pulling in great ratings in anticipation of his Feb. 6 goodbye. Last night’s installment of The Tonight Show equaled its best overnight rating in 15 months: Leno scored a 3.9 rating in metered markets, his best performance since Oct. 24, 2012, according to Nielsen.

Last night’s episode, which featured a visit by heir apparent Jimmy Fallon, was also the highest Monday rating since March 1, 2010 (when it earned a 5.4).

Afterwards, Fallon earned a 2.0 in overnights, his highest rating for a Monday since March 1, 2010.
